WebClassification of earthquakes Starting from the earlier years of the human history generally to evaluate the intensity of the earthquakes is used to observe them according their effects to the environment (destruction, damages) But generally, in these comparison there were many subjective factors based on the human feelings. Tectonic earthquakes occur anywhere in the earth where there is sufficient stored elastic strain energy to drive fracture propagation along a fault plane. The sides of a fault move past each other smoothly and aseismically only if there are no irregularities or asperities along the fault surface that increases the frictional resistance. Most fault surfaces do have such asperities, which leads to a form of stick-slip behavior. Once the fault has locked, continued relative motion between the plat…
